Merge tag 'char-misc-5.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc 

Pull char/misc driver fixes from Greg KH:
 "Here are some small char and misc driver fixes for 5.3-rc5.

  These are two different subsystems needing some fixes, the habanalabs
  driver which is has some more big endian fixes for problems found. The
  other are some small soundwire fixes, including some Kconfig
  dependencies needed to resolve reported build errors.

  All of these have been in linux-next this week with no reported
  issues"

* tag 'char-misc-5.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc:
